200% increase from 60 to 180
180 is 90% of 200
10% of $200= $20 $200-$20=$180
10% off of 200 leaves 90% of 200 = (0.9 x 200) = 180
180 would be 200% of 90 90 would be 50% of 180 I do not know which you meant
200 * .05 = 10200 - 10 = 190kg
50%
It is: 90% of 200 =180
18010% off of $200= 10% discount applied to $200= $200 - (10% * $200)= $200 - (0.10 * $200)= $200 - 20= 180
90% is equal to 0.90. Therefore, asking "what is 90% of 2.00?" is the same thing as asking "what is 2.00 * 0.90?". 2.00 * 0.90 = 1.80 If you were unsure about how to go about solving this problem, there was an even easier way to do it. You know that 90% of one is 0.9, and you know that two is twice the size of one. Therefore, 90% of two would be 180% of 1, or 1.80.
200 to 180 is a 10% decrease.
It is: 180/200 times 100 = 90%
